To provide with an effective method for computer generated images with artistic appearances from 2D images motivates our work in this paper. We mainly propose the method for generating the artistic appearances based on the deviation mapping technique. As the preprocessing of the deviation mapping, the texture synthesis can be fulfilled to produce the background image with the same size of the foreground...
Aimed at the excellence and shortcoming of the traditional median filtering algorithm, this paper proposes a new adaptive weighted median filtering algorithm. The new algorithm first determines noise points in image through noise detection, then adjusts the size of filtering window adaptively according to number of noise points in window, the pixel points in the filtering window are grouped adaptively...
Image fusion technique has been widely applied to remote sensing image analysis and processing and the aim of the image fusion is to integrate the characteristic information of each image. By uniting the useful information a new image can be formed to improve the visual impression, and one can get a more accurate, comprehensive and reliable description for the same scene. In the traditional IHS transform...
This paper puts forward a novel method using dynamic programming and grey relational analysis to find a best seam line because of the grey scale difference in the edges of image in the overlapping region and the relation of neighboring points. The first step is to find an optimal seam line to stitch the images. Then the seam line is removed by a hard correction method based on dynamic width. Finally,...
The aim of this study was to establish a method of automatic side face portrait recognition based on Fourier descriptor. The method consisted of three steps: face outline extraction, Fourier descriptor feature extraction and feature comparison. In the step of face outline extraction, the background was separated from the face first so as to get the overall face contour line, and then, determined two...
To achieve efficient image retrieval, this paper applied the five texture edge directions, including 0deg, 45deg, 90deg, 135degand nondirection, recommended by MPEG-7 standards to generalized co-occurrence matrix method. The new method firstly constructs five generalized co-occurrence matrices by computing the neighboring average of pixels in a fixed window in five directions respectively. And then...
Sudoku, a simple and fun game of logic, has been used for steganography to conceal messages into a digital image recently. Chang et al. adapted the idea of smallest Manhattan distance, embedding secret messages into the neighbors of the located element according to a given Sudoku solution. Hong et al. improved Chang et al.psilas technique by introducing additional set of candidate elements to reduce...
The paper associates fractal dimension with the image disorder degree, which is introduced into pre-classification for fractal compression coding process together with the concept of quartered-tree coding, then a fractal compression coding approach based on fractal dimension feature blocks is brought forward. The algorithm improves coding time, compression ratio, but the peak-peak signal-noise ratio...
This paper proposed an adaptive shadows detection algorithm based on Gaussian Mixture Model to improve the performance of video object segmentation. This method takes advantage of luminance weight to model the background of the image and obtains a primary segmentation in CIE Luv color space. In this way, it improves the real-time ability of detection. It also becomes more efficient, comparing with...
